ASE LIGHT SOURCE

A high-intensity amplified spontaneous emission (ASE) light source that covers the 1480- to 1580-nm band is available from NTT Electronics Corp. Suitable for use in WDM communications, this light source enables the development, evaluation and measurement of optical devices for the S-band. The company says that utilizing thulium-doped optical fiber amplifiers allows the device to emit light efficiently and with high intensity. Other Tm-doped devices available include an optical fiber module for optical amplifier use and an optical gain module.
